The Active Ingredient Is: Vitamin C (Ascorbic Acid)

Vitamin C, or ascorbic acid as it's often called, is a water-soluble nutrient essential for normal connective tissue formation and immune function. This form is widely used for its antioxidant powers and to support mucosal surfaces. This formula also includes zinc and botanicals that help support the immune system overall.

What Does Vitamin C Do?

Vitamin C helps the normal function of the immune system and protects cells from oxidative stress. It helps support mucosal barrier integrity, with evidence suggesting it participates in immune cell activity. Dr Hemilä from University of Helsinki found that higher intake can be linked to shorter cold duration in some people.
